Question 1

What parts are in GigaGeek’s $5000 all-white gaming PC build?

Accepted Answer

I built this one with an i9-14900K, a Gigabyte RTX 4090 AERO, and a Gigabyte Z790 AORUS Pro X motherboard. For memory I went with 64GB of Corsair Dominator Platinum RGB, and storage is a Samsung 990 Pro. It’s all housed in the Lian Li O11 Dynamic Mini Snow White with an NZXT Kraken Elite 360 RGB and a bunch of Lian Li UNI SL120 fans.

Question 2

Why did you choose the i9-14900K for this build?

Accepted Answer

Because this PC had zero compromises, and the 14900K is exactly that kind of CPU. You’re getting 8 performance cores, 16 efficiency cores, and it can push up to 6GHz on the P-cores. It’s the kind of chip that rips through gaming, editing, trading workflows, and CAD rendering without flinching.

Question 3

Is the Gigabyte Z790 AORUS Pro X good for an all-white build?

Accepted Answer

Yes—this board looks insane in a white theme, and that’s a big reason I picked it. A lot of “white” boards still have a black PCB that throws off the aesthetic, but Gigabyte went the extra mile with a fully white PCB. On top of that, it’s a high-end Z790 with strong VRM and really nice quality-of-life features for building.

Question 4

Why is your AIO mounted on the bottom in the O11 Dynamic Mini?

Accepted Answer

In this case layout, top mounting ran into the I/O cover because of the smaller form factor and the clearance I had. So I mounted the Kraken Elite 360 on the bottom and used it as intake. The nice part is it actually helped temps—during my testing the CPU peaked around 85°C, which is terrific for a 14900K.

Question 5

How many fans did you use and why Lian Li UNI SL120?

Accepted Answer

I used eight Lian Li UNI SL120s because I love the SL series for clean builds. They use an RGB strip instead of the whole fan glowing, and that keeps the look minimal and classy instead of turning into an RGB explosion. It fits my design style where it’s performance-first but still visually balanced.

Question 6

What power supply do you need for an RTX 4090 + i9-14900K in the O11 Dynamic Mini?

Accepted Answer

Since the O11 Dynamic Mini uses SFX/SFX-L on the side (no bottom PSU compartment), you need a unit that fits that size requirement. I went with the Corsair SF1000L 1000W because the 4090 and 14900K are both power-hungry. Beyond that, the key is matching the form factor and giving yourself enough wattage headroom.

Question 7

Is a vertical GPU mount worth it for this case?

Accepted Answer

For this build, absolutely—because I wanted to show off the 4090 AERO in all its glory. Installing the bracket was kind of a pain since I had to tear down a lot of the back of the case, but the end result looks amazing. Also, I recommend the PCIe 4.0 riser version to avoid compatibility issues.
